No one wants to spar with Robbie. I remember Pat Militech saying on a strike force broadcast that he didn't want to spar with Robbie anymore because he hits like a truck and doesn't want brain damage. This is like when Robbie is only going 60-70 percent. He's a beast. I honestly think he can compete with heavyweight punchers. Kinda like how MANHOEF was.
I wouldn't wanna spar with Overeem. He probably hits like a truck too.
